A Cdc42 ortholog is required for penetration and virulence of Magnaporthe grisea
Fungal Genetics and Biology, 2009Cdc42, a member of the Rho-family small GTP-binding proteins, is a pivotal signaling switch that cycles between active GTP-bound and inactive GDP-bound forms, controlling actin cytoskeleton organization and cell polarity. In this report, we show that MgCdc42, a Cdc42 ortholog in Magnaporthe grisea, is required for its plant penetration.

Having a blast: exploring the pathogenicity of Magnaporthe grisea
Trends in Microbiology, 1995The rice blast fungus Magnaporthe grisea has an exquisite level of pathogenic specialization, allowing it to infect and colonize rice, subvert the metabolism of the host and spread to new hosts. Through a combination of cytology and molecular-genetic analysis, a picture is gradually emerging of the many interlinked processes that are required for ...

The Effect of Magnaporthe Grisea Toxin on Photosystem in Rice
Advanced Materials Research, 2013Understanding the toxic effect of Magnaporthe oryzae on rice to breed resistant varieties is important for environment protection. The effects of four M. Oryzae physiological races were conducted on the photosynthesis and photosynthetic pigment contents relating to hybrid rice.

Screening and identification of mutants of Magnaporthe grisea by REMI
Frontiers of Agriculture in China, 2007The plasmid pUCATPH was used to establish a transformation system in wild-type isolate M131 of Magnaporthe grisea. Six hundred and thirty-nine transfor- mants were obtained by restriction enzyme-mediated integra- tion (REMI) with hygromycin B (hyg B) resistance as a tag.

Disruption of a Magnaporthe grisea cutinase gene.
Molecular & general genetics : MGG, 1992Using a one-step strategy to disrupt CUT1, a gene for cutinase, cut1- mutants were generated in two strains of Magnaporthe grisea. One strain, pathogenic on weeping lovegrass and barley and containing the arg3-12 mutation, was transformed with a disruption vector in which the Aspergillus nidulans ArgB+ gene was inserted into CUT1.

The Rice Blast Fungus, Magnaporthe grisea
1997Magnaporthe grisea (Hebert) Barr (Barr 1977; Yaegashi and Udagawa 1978) is a filamentous, heterothallic Ascomycotina that collectively causes disease on many species of the grass (Poaceae) family. M. grisea is the teleomorph corresponding to the previously distinct anamorphs Pyricularia oryzae, infecting rice (Oryza sativa), and P.

RNA Silencing in the Blast Fungus Magnaporthe Grisea
2004We have examined RNA silencing in the blast fungus Magnaporthe grisea using the green fluorescence protein (GFP) gene as a model. The fluorescence in the GFP transformants was efficiently silenced by introducing a plasmid expressing double-stranded GFP RNA. Consequently, GFP mRNA accumulation was drastically reduced in the silenced transformants.

Genetics of Fertility and Mating Type in Magnaporthe Grisea
2004Blast disease of rice (Oryza sativa L.) caused by Magnaporthe grisea (anamorph = Pyricularia grisea) is one of the principal disease of rice. M. grisea includes a large number of monocots among its host range, however individual isolates are specific to only one or few hosts species.
